Intestinal Permeability Test – Cyrex Labs Array #2

“Leaky Gut Test” | Cyrex Labs Array #2

In many people, gluten and other food proteins cause inflammation in the gut, which eventually leads to intestinal permeability, or “leaky gut”. Leaky gut allows undigested food particles, bacteria, and other materials to enter the bloodstream where they can trigger the immune system creating allergies, sensitivities, and inflammation in other parts of the body.

There are several different ways leaky gut can occur:

  • Breakdown of intestinal cells
  • Loosening of the junctional between cells
  • Bacterial infections
